Preventing birth defects, ultrasound AI to help

According to the 2010 Global Cover (GBD) study, 6.4%of newborn deaths are due to birth defects and ranked fifth among all causes of death. How to prevent child birth defects is a topic that every family cares about.

The Sixth Police Diagnosis Academic Conference of the Guangdong Medical Association was held in Guangzhou from July 1st to 3rd. The reporter was informed that the result of the ultrasound examination in the hospital in the hospital will have huge subjective differences. For example, the level of skills of the doctor's subjective grasp and the reading and judgment of ultrasonic images may be missed, and the new technology ultrasound AI intelligent system can help solve this problem. At present, the ultrasonic AI intelligent system has been used in more than 100 high -level hospitals across the country at the First Affiliated Hospital of Sun Yat -sen University, and the Guangdong Maternal and Child Health Hospital. Experts appealed that it hopes that ultrasonic AI can be used in a large scale as soon as possible. Precisible screening of prenatal screening to avoid the birth of severe birth defects, ensuring the health of pregnant women and the normal development of the fetus.

The total incidence of defects in my country is about 5.6%

In recent years, with the continuous improvement of the prevention and control system for birth defects in my country, the three -level prevention and control measures have been implemented in depth, and the prevention and control of birth defects has achieved certain results. The "China birth defect prevention report" released in 2012 shows that the total incidence rate of birth defects in my country is about 5.6%.

Birth defects, that is, the "congenital malformations" in popularity, refer to abnormal body structure, function or metabolic abnormalities that occur before the baby is born. Birth defects can be caused by genetic factors or environmental factors such as chromosomal distortion, gene mutations, etc., or interact with these two factors or other unknown reasons. Common birth defects include congenital heart disease, limb deformity, hydrocephalus, lip cracks, multi -finger, neurooth tube deformity, etc.

The birth defect is the main cause of early abortion, death, siege, death, infant death, and congenital disability. It not only seriously endangers the quality of children's survival and quality of life, but also causes huge potential life losses and social and economic burdens. Birth defects have become a public health problem that affects the quality of population and the level of group health. If appropriate intervention measures are not taken in time, birth defects will seriously restrict the further decline in the mortality rate of infants in our country and the improvement of per capita expectations.

There are three levels of prevention and control in birth defects

Professor Xie Hongning, chief physician of the Obstetrics and Gynecology Ultrasound Department of the First Affiliated Hospital of Sun Yat -sen University, introduced that in order to cope with birth defects, my country established a third -level prevention system. Among them, secondary prevention is currently the most important, that is, the screening of pregnancy and prenatal diagnosis.

According to the National Health and Health Commission issued the "Comprehensive Prevention Plan for National birth defects" issued by the National Health and Health Commission in 2018, the implementation of comprehensive prevention and control measures for birth defects is required, and the third -level prevention is mentioned: first -level prevention is to implement pre -marital inspections and pre -pregnancy eugenic students in different marriage and childbearing stages. Health examination, supplementation of folic acid, and health care during pregnancy; secondary prevention is to attach importance to the screening of pregnancy and prenatal diagnosis, which can identify the congenital defects of the fetus early and reduce the birth of defective children; It is necessary to pay attention to the tracking, diagnosis, treatment, and intervention of newborn disease screening to investigate positive cases to facilitate timely treatment and improve the health level of children.

Professor Xie Hongning said that ultrasound examination is the most important content in pregnant women's maternity examinations. During the entire growth and development monitoring process of the fetus, prenatal ultrasound is an irreplaceable examination, and it is almost the only image test that can be done for pregnant women to directly observe whether the fetus has a test of birth defects. Only after the ultrasonic examination is discovered by abnormalities, can we guide pregnant women to do genetic testing, pumping of amplifiers, chromosome and other testing.

Ultrasonic AI helps improve the accuracy of prenatal screening

However, the result of an ultrasound examination in the hospital in the hospital will have huge differences in subjective judgment. For example, the level of skills of the doctor's subjective grasp and the reading and judgment of ultrasonic images may be missed.

To solve this problem, the ultrasonic AI analysis system came into being. The system is jointly developed by a number of three -armored medical institutions including Zhongshan University Affiliated Hospital, as well as institutions such as the School of Computer Science and Technology of South China University of Technology. Dr. Wang Nan, executive director of the Guangdong Ultrasound Medical Engineering Association, introduced that as long as the system is placed on the hands of ultrasound doctors, he can provide a real -time synchronization analysis result for ultrasound doctors. The purpose of quality control and improvement.

The First Affiliated Hospital of Sun Yat-sen University has held three consecutive human-machine competitions since 2019-2021 to simulate the scene of clinical usage. Among them, the third human -machine competition was held at the ultrasound department of the First Affiliated Hospital of Sun Yat -sen University. "The abnormal sound of the craniocerebral standard cut" was published in the most authoritative magazine "Self -Gynecological Ultrasound" in the international field of obstetrics and gynecology.

In addition, in December 2021, the Guangdong Maternal and Child Health Hospital also held a human-machine contest containing 36 doctors from different hospitals at different hospitals. The results of this human-machine contest showed that doctors using AI can improve diagnostic ability and reduce 6%-10 The leakage rate of %, related research papers are being written.

Tips: How to prevent birth defects?

Preventing birth defects, in addition to people's more familiar active marriage inspections, pregnancy inspections, regular production inspections, and supplementation of folic acid, according to the "core information of birth defect prevention and control of health education" issued by the National Health Commission, the following aspects should also be paid to the prevention of birth defects: 1. 1. Age -age fertility, scientific pregnancy preparing for pregnancy

Women over 35 years of age are pregnant as an elderly pregnancy, which will increase the risk of endless pregnancy ending during pregnancy hypertension, diabetes, and embryo stopping, miscarriage, fetal birth defects.

Reasonable meals during pregnancy, exercise in moderation, maintain suitable weight, regular work, relax, quit smoking and alcohol, avoid contact with second -hand smoke, stay away from drugs and addictive medicines, and develop healthy living habits and behaviors.

2. Avoid contact with toxic and harmful substances

Preparation women should take 0.4 mg folic acid or compound vitamins containing 0.4mg of folic acid every day from 3 months before pregnancy, at least 3 months after pregnancy to reduce the risk of fetal nerve tube defects. Consult the policy of receiving free folic acid with the local maternal and child health care institutions.

6. Several anemia areas to screen for screening

Fujian, Jiangxi, Hunan, Guangdong, Guangxi, Hainan, Chongqing, Chongqing, Sichuan, Guizhou, Yunnan and other regions have a high carrying rate for Mediterranean anemia (poverty) genes. The sooner the better, to understand whether you are carrying poverty -poverty. The high -risk couples screened should be diagnosed prenatal diagnosis to avoid the birth of heavy poverty -stricken children.

7. Screening of Tang's syndrome should be accepted during pregnancy

Pregnant women should choose to conduct a pre-production of Tang's syndrome at 12-22 weeks of pregnancy. Pregnant women over 35 years of age should go to a qualified medical institution for prenatal diagnosis.

8. Newborns should be screened in time after birth

After the birth of the newborn, the screening of diseases such as phenoloneuria, congenital thyroid dysfunction, and hearing disorders should be accepted in time to promote early detection, early diagnosis, and early treatment of congenital diseases; Essence
